I'm running virtualbox 4.1.2 on centos 4.9 with the following kernel: 2.6.9-101.ELsmp #1 SMP Thu Jul 21 17:46:19 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux.
When the system boots, I get the following error in the log: vboxnetflt: no version for "VBoxHost_RTSpinlockCreate" found: kernel tainted.
When I'm running a centos 6 guest with almost no load, the system will run for a couple of days, then the server will reboot with a hyperthreading error. It doesn't do this if I dont start Virtualbox. Anyone know of a fix?
